1. Whether there is a product hygiene license approval.
The quality of the water purifier is very important, it is necessary to comply with the provisions of the measures for the supervision and management of drinking water sanitation, obtain the health license of the superior health supervision department, and after the identification of the technical supervision department, the water purifier that meets the national "drinking water quality standards" is trustworthy.
2. Whether it has safe and effective sterilization technology.
Water purification equipment uses two ways to sterilize, one is to add disinfectant, which can kill some bacteria, but the disinfectant contains trace amounts of chemical components that are harmful to human health; The second is ultraviolet sterilization, which is one of the most effective sterilization technologies recognized internationally.
Because ultraviolet sterilization is safe and efficient, it can quickly kill almost all bacteria, and ultraviolet sterilization uses physical principles to sterilize, without any chemical agents, and will not have any effect on the human body.
3. Choosing the right filter element is crucial.
The first generation of water purifiers are mainly filtered through activated carbon, ceramics, etc., which are easy to breed bacteria, pollute water sources, and cannot achieve the effect of clean water sources; The second-generation water purifier uses a variety of artificial polymer membrane filtration, which has a significant effect on removing harmful substances in the water, but its fatal flaw is to filter out trace elements that are beneficial to the body.
The third-generation water purifier adopts nanocrystalline filter technology, which solves the defects of the second-generation water purifier and filters out harmful substances and heavy metals in the water. Therefore, when you choose a water purifier, you must ask about the filtration technology and filter material used to see if it meets your own needs.
4. Whether it has a perfect after-sales service system.
After buying some brands, many consumers can't find the address of the maintenance service** or the repair service company, which makes consumers very helpless and causes a waste of resources, and many water purifiers have become furnishings.
The after-sales service of the water purifier mainly focuses on the replacement of the filter element, if the filter element is not replaced for a long time, it will pollute the water source, and the water purifier will also become a "sewage device". When choosing a water purifier, you must choose a manufacturer with perfect after-sales service, such as using a customer service system to track customer information and prompt customers and companies to replace filter cartridges.
5. The purchase performance ratio is high.
The structure of the water purifier is different, and the water purification effect is also different. Generally speaking, the structure of the primary filtration water purifier is simple, mainly activated carbon, its filtration capacity is limited, and it can only be used for coarse filtration, and the filtered water is best heated and boiled for drinking. Most of the first-level filtration water purifiers are low-grade water purification products, and the price of each unit is between more than ten yuan and 150 yuan.
The multi-stage filter water purifier has two stages of coarse filtration and a set of fine filtration, and the fine filtration mostly adopts a hollow fiber filter element, and the filtered water can be directly drinkable. Multi-stage filter water purifier is a mid-range water purification product, each priced between 300 yuan and 500 yuan, which can be accepted by the working class and used more by families.

It depends on the filter element, not all water purifiers can produce direct drinking water, and the purification effect of some filter elements cannot meet the standard of direct drinking water, if it is direct drinking water, you need to buy RO reverse osmosis water purifier, which is the kind of Haier I use at home, which is very suitable for our friends who like to drink room temperature water.

Water is the source of life, without water, my body function will decline in the loss of water, but now there is a problem that worries everyone in the world, that is, water pollution has affected our domestic water, more than half of China's urban water has been seriously polluted, and the pollution of the water underneath is still continuing, what should we do to save it? Many families are already using water purifiers to purify water quality, but there are still many friends who don't know about water purifiers, today I will tell you how to choose a water purifier, let's take a look!
1. How to choose a water purifier: understand the local water quality.
Is there some doubt when you see this, is it also related to the quality of the water when you choose a water purifier? In fact, each different water purifier, the filter element is different, so the filtration effect is different, suitable for different water quality, take the difference in water quality between the north and the south, the water quality in the south is softer, there are more heavy metals, and it is more appropriate to choose a pure water machine. The water quality in the north is harder and more impurities, so you can choose a resin filter with ion exchange.
2. How to choose a water purifier: understand the location, size and method of installing the water purifier at home.
When it comes to choosing a water purifier, you will still be very flustered, and now the water purifier is generally hidden in the cabinet under the pool, so it is best to choose a good location before decoration, or reserve a place for installation.
3. How to choose a water purifier: understand the brand and qualification of water purifier.
If you want to buy a water purifier, it is not recommended to buy a miscellaneous brand of production, there may be quality, performance is not guaranteed, choose the brand, you can use it with confidence, here I will not recommend the brand to you, because there are really a lot, if you choose a domestic brand, you should pay attention to see if the brand has registered the health license endorsed by the national department and the identification of the supervision department, and it must meet the national "drinking water quality standards".
4. How to choose a water purifier: the price comparison of water purifiers.
Paying attention to ** is what consumers should do, and the water purifier with high cost performance will definitely be recommended by everyone, but because the market of water purifiers is not standardized enough, there is no unified standard, but everyone should remember that the ** of water purifiers has an impact on the filter material and technical quality, and has nothing to do with the number of filter elements.

1. If there are many members in the family and the demand for drinking water is large, it is recommended to choose a water purifier with no barrel fiber and large flux.
2. If the installation space at home can be met and the demand for drinking water is not large, you can choose a water purifier with a bucket.
3. If there will be special circumstances such as water and power outages at home, you can choose a water purifier with a bucket to facilitate the filtered water in the bucket to drink first when the equipment cannot work.
4. The last suggestion is that Gao Accompany should choose products with good brand reputation, product quality, filter elements or accessories and other materials, and excellent after-sales service, in order to solve problems easily and effectively.

Different types of water purifiers should be selected according to the different water quality.
Water purifiers are also called water purifiers and filters, which are used for sewage treatment. The water purifier usually refers to a small filter used for household use, and the commonly used water purifier can be divided into the following categories according to different water quality treatment methods:
Magnetization refers to the use of the magnetic field effect to treat water, known as the magnetization of water.
Mineralization refers to the addition of mineral elements (such as calcium, zinc, strontium and other elements) that are beneficial to the human body to the water on the basis of purification. Commercially available water purifiers generally achieve the purpose of mineralization by adding maifan stone to the water purifier.
Ozone and ultraviolet sterilization can only sterilize, but cannot remove heavy metals and chemicals in the water, and the corpses of the bacteria that have been killed are still left in the water and become pyrogens.
The electrolysis method of electrolysis of purified water began in Japan, and this equipment is called water ionizer.
Activated carbon adsorption can be divided into three forms: granular activated carbon, granular activated carbon, and fiber activated carbon.
RO reverse osmosis membrane is a kind of pure water machine that can be directly drunk by human beings after filtering the raw water (physical method) without adding any compounds through the current international popular reverse osmosis and other methods, also known as terminal water purification equipment.
Compound typeWhen it is difficult to remove harmful substances in water in one process, two or more processes are used for compound type, which has become a hot spot in the current development of water purifiers.
The design and manufacture of water purifier is a comprehensive science and technology, in terms of the characteristics of water quality in various regions of China, the organic matter pollution along the Yangtze River and densely populated areas is serious, so only some high-quality water purifiers can adapt to different water quality across the country, so water purifier manufacturers should be based on the water quality conditions of different regions, carefully designed to adapt to different water sources, but the treatment effect is good water purifier.
Commonly used water purifiers in households include magnetized water purifiers, activated carbon adsorption water purifiers, and composite water purifiers. Magnetized water purifier is suitable for families with less tap water quality and debris, activated carbon adsorption water purifier is suitable for families with more tap water impurities, and the composite water purifier has a complex principle and can filter harmful substances while simply filtering tap water, which is suitable for families with water pollution in tap water.

First: choose a water purifier according to the age structure of the family: At present, there are many kinds of water quality produced by water purification on the market, and the merchants have never stopped fooling consumers, and they are endless.
There are two main types of water purifiers on the market, purified water and mineral water. These are also the two types of water quality that are currently standard in the country. If there are children in the family, it is recommended to use purified water equipment, because the child's body absorption capacity is insufficient, and there is a hidden danger of mineral accumulation after drinking for a long time.
If you don't have children, you can do both. The visual manifestation of these two types on the equipment is whether the last stage of filtration consumables is activated carbon or mineralized balls. As for what some businesses advertise about weak alkaline and active water, I don't believe it anyway, as for whether you believe it or not, I don't know.
The state's requirements for water quality are that neutral water is drinkable, and as for the acidity and alkalinity in the production of large-scale equipment, it is only adjusted according to the requirements of water production. As for active water, you should understand that the structure of water molecules is an angle of 105°.
Second: choose a water purifier according to the consumables of the equipment: the main consumables of the main water purifiers on the market are RO (reverse osmosis membrane) UF (central control fiber membrane, which is what we often call ultrafiltration membrane).
The permeate quality of RO membrane can remove heavy metals, particulate impurities, residual chlorine in water, rust, bacteria in water, etc. Ultrafiltration can also achieve the function of removing rust, residual chlorine and impurities, but the purity of the removal is not as high as that of RO.
There is also a view in the market that the substances in the water are too clean and not good for the body. First of all, everything is mutually reinforcing. Both RO and UF are physical filtration, which is filtered according to the accuracy of the impurities in the water quality, and while the UF retains the substances that are beneficial to the body, the harmful substances must also be retained.
According to some experts, the amount of various beneficial substances contained in a glass of milk from an egg is many times higher than the amount of substances contained in the water you drink for a day, as for the specific data, I forget. Thank you for your understanding.
As for the brand, I don't believe in it, my reason is that everyone is the same principle, the same configuration and assembly method, and the different is the name of the manufacturer and equipment of the accessories.
The simplest thing is that we went shopping the day before yesterday and saw a well-known brand promoting in the market, the price was marked at more than 7,000, and it was not discounted, I asked about the configuration, calculated it, and the cost was less than 500 yuan. Therefore, when buying these new products, you must maintain your own sanity and initial understanding of the product.

How to choose a household water purifier?
1. In terms of style, there are distinguished: a single type or mixed water purifier with a single-cylinder stainless steel shell, a 3+2 old model with two filter elements erected below the three filter cartridges, and an integrated type with a shell box structure for the whole machine.
In general, the water purifier with integrated box structure has the best performance.
2. Look at the product name: Choose the "self-cleaning" water purifier, which is the most convenient and worry-free to use, and the performance of the self-cleaning water purifier is better than that of various automatic sewage water purifiers seen on the market.
3. See if there is a double membrane protection design.
The double membrane water purifier is much better than the ordinary water purifier, and if it is a double membrane protection design, it is more superior.
4. Choose a water purifier with low energy consumption.
Look at the interface is one in and two out, the water purifier that can achieve quality water supply has low energy consumption, and at the same time, choose a water purifier with no or less waste water, no electricity and low annual replacement consumables cost.
The self-cleaning water purifier is the only national property rights protection product on the market that can meet the above 4 points at the same time.

How to choose a water purifier? What are the issues to be aware of?
1.Choose a water purification effect with a good water purification effect, and the water purification effect of the water purifier depends on its filter element and filtration method. Common filter elements include PP cotton, high-precision PP cotton, carbon fiber, activated carbon and reverse osmosis, among which reverse osmosis has the best filtration effect. , as close to pure water as possible. As mentioned earlier, this water purifier uses a high-precision reverse osmosis filtration system, which can effectively filter harmful substances such as impurities and heavy metals. And the use of food-grade 316L stainless steel vacuum liner, not only healthy and safe, but also can maintain a constant temperature for a long time.
2.Look at the brand, a good brand will have a regular brand official website, and general information can be found on the Internet. We need to know the history of the brand, the place of production, the main cases, the exact technical parameters of each product, etc.
The focus of buying any product is inseparable from the brand, and it can also be comprehensively evaluated from the aspects of market share, water purification effect, ease of use, evaluation, etc.
3.How to use electricity, plug-in Most water purifiers are plugged in, do not retain minerals, and are suitable for areas with poor water quality; Unplugged and available at any time, it can retain water, some beneficial minerals and trace elements do not produce wastewater, and the filtration capacity is high, which is suitable for areas with good water quality;
4.When choosing a water purifier, you need to pay attention to the filter element, and the membrane water purifiers on the market are mainly divided into three types: microfiltration, ultrafiltration and reverse osmosis. The filtration accuracy is from low to high.
Microfiltration water purifiers belong to ordinary filtration, which can generally only filter large suspended solids. , odor removal, etc. The filtration effect of the ultrafiltration water purifier is in the middle position, and the filtration accuracy and water purification effect of the reverse osmosis water purifier.
Individual enterprises such as Robam Appliances have double reverse osmosis membrane water purifiers, and the water purification effect is more prominent. The ** of microfiltration, ultrafiltration, reverse osmosis, and double reverse osmosis water purifiers are also from low to high, please choose according to your budget.
5.When choosing a water purifier, you need to pay attention to after-sales service, some water purifiers look cheap, but the cost of replacing consumables may be very high, and there is no after-sales service, but some water purifiers are very expensive to buy for the first time, so you don't have to worry about them later. Water purifiers are different from other products, and perfect after-sales service is required to ensure the later use and effect of water purifiers.
Therefore, after-sales service is more critical, don't ignore this, otherwise there will be endless troubles.
The details are as follows: At present, water purifiers have been developed in China for more than ten years, and the industry has formed a mature industrial chain system. Especially in recent years, the popularity of smart home has also stimulated the development of water purifiers and other related industries, especially in 2015 and 2016, the water purifier industry has developed rapidly. >>>More
Filter element: The filter pore size is large and small, generally about microns. >>>More
The consumables of the water purifier are generally replaced once every one and a half to two years, which will affect the quality of the effluent after a long time.
Determine the design flow rate and head, as well as the diameter and type of the pump, and use the "Pump Performance Table" to select the pump model. >>>More
The design of the nanofiltration membrane process is rigorously validated, rigorous, and standardized. The control is accurate, the automatic control design is perfect, the effect is stable, and the maintenance is convenient. >>>More
